( Goto
your manifest.xml and take package ex: package="your_project_pcakge_name")
Then
click create button, Google Maps API V2 key

3) In Your Project add some additional code
i)In your manifest.xml:
We need some permissions, feature and Meta
Tag
Meta Tag:
Add
this meta tag in your before closing </application> tag in manifest.
<meta-data
android:name="com.google.android.maps.v2.API_KEY"
android:value="Write_ur_Google_Maps_API_Key" />
Note: Write your Google Maps API key in meta
tag ( previous step you got key)
Permissions:
<permission
android:name="replace_ur_package_name.permission.MAPS_RECEIVE"
android:protectionLevel="signature"
/>
<uses-permission
android:name="replace_ur_package_name.permission.MAPS_RECEIVE"/>
Also add these permissons:
<uses-permission
android:name="android.permission.INTERNET" />
<uses-permission
android:name="android.permission.ACCESS_NETWORK_STATE"/>
<uses-permission
android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

Feature:
Add
this feature
<uses-feature
android:glEsVersion="0x00020000"
android:required="true"
/>
ii)In your layout activity_main.xml file:
Add
this code
<fragment
android:id="@+id/map"
android:name="com.google.android.gms.maps.SupportMapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"
/>
Here i
use SupportMapFragement because its support All versions
iii) Your Class Must extends with FragmentActivity and add this code also
SupportMapFragment
smf = (SupportMapFragment)
getSupportFragmentManager().findFragmentById(R.id.map);
GoogleMap
map = smf.getMap();
Run Your Project into device you got a Map like this way
Show Current Location:
// enable current location
map.setMyLocationEnabled(true);
Add Marker:
double lati = 17.388321, longi =
78.487869;
LatLng
position = new LatLng(lati, longi);
// Add
marker to map
Marker marker = map.addMarker(new MarkerOptions()
.title("Hyderabad")
.icon(BitmapDescriptorFactory
.defaultMarker(BitmapDescriptorFactory.HUE_AZURE))
.position(position));
Move to
Marker position:
// move camera to position
map.moveCamera(CameraUpdateFactory.newLatLng(position));
Zoom Marker
position:
// zoom controls
map.moveCamera(CameraUpdateFactory.newLatLngZoom(position,
10));
Add
Listener for Marker:
// add listener for marker
map.setOnMarkerClickListener(new OnMarkerClickListener(){
@Override
public boolean
onMarkerClick(Marker marker) {
Toast.makeText(ctx, "U
clicked Markar", 3000).show();
Intent
it = new Intent(Intent.ACTION_VIEW);
it.setData(Uri.parse("http://venkoolit.blogspot.com"));
startActivity(it);
return false;
}
});
Add Polyline:
map.addPolyline(new PolylineOptions().add(
new LatLng(17.498211000000000000,
78.409864799999920000),
new LatLng(17.346480600000000000,
78.550958300000050000))
.geodesic(true));
Show Traffic:
// enable trafic
map.setTrafficEnabled(true);
Change Map
Type:
// set map type satellite
map.setMapType(map.MAP_TYPE_SATELLITE);
